BLK202A-BK Application Field and Working Principle

Introduction:

BLK202A-BK is a LED display module from Tyco Corporation. It is mainly applied in small applications such as message indication, indicators, displays in computers and instruments, as well as small liquid crystal displays. It is a part of Tyco’s family of miniature LED displays.

Application Field:

BLK202A-BK displays in the following areas of application:

• Industrial control and instrumentation:
• consumer electronics in the form of calculators and watches;
• general consumer electronic devices, such as portable multimedia players;
• medical or veterinary applications;
• marine, automotive and aerospace applications.

The displays are found in consumer and commercial applications, where the displays indicate the system status and provide monitoring. In addition, there are applications in security and home automation.

Working Principle:

BLK202A-BK is a liquid crystal display module with an integrated circuit. It features a serial memory which can be used to store data and commands. The serial data is received and stored in the memory, and then sent to the LCD driver. The LCD driver controls the LCD and can also send back commands.

The display module is based on the LCD Dot Matrix Structure pixel material. Each pixel consists of three different colored vertical segments. The display is driven by an integrated circuit (LED controller) which is programmed to control which of these three segments are lit up in order to display numbers, letters, and graphical images. The LED controller also includes an EEPROM memory which is used to store color settings. The LED controller is programmed with an LED control circuit and a user interface, which allows it to be programmed to display a variety of different characters and images.

The BLK202A-BK comes with a wide viewing angle. It has a viewing angle of 178° horizontally (H) and 178° vertically (V). This is important for viewing text and graphically rich displays, as it ensures that viewers see all the details.

Conclusion:

BLK202A-BK is a LED display module from Tyco Corporation designed for small applications such as message indication, indicators, and displays in computers and instruments. It offers a wide viewing angle of 178° horizontally and 178° vertically. It is mainly found in consumer and commercial applications, where the display indicates the system status and provides monitoring. The display also includes an integrated circuit and an EEPROM memory which can be used to store data and commands.
